Boasting is verbalized pride. It is self-commendation, bragging to others of our accomplishments. However, all that actually matters is what God thinks of us, not what others think.
Boasting is the exact opposite of the meekness and gentleness of Christ. Paul refused to boast about his personal appearance, power, or accomplishments. Instead, he pointed out that his strength was a hidden force, unnoticed by the world but divinely powerful (2 Corinthians 10:3-4).
Paul used his God-given authority, not for destruction, but for building up (2 Corinthians 10:8). He gave reports about the mission work he had accomplished, not to brag about what he had done, but to show what had been done by the grace of God. Without a doubt, Paul knew that “the person who wishes to boast should boast only of what the Lord has done” (2 Corinthians 10:17).
Isaiah foresaw a day in which “pride will be brought low and the Lord alone will be exalted” (Isaiah 2:11). Satan’s proud, boasting spirit will one day be brought low, and no one will dare utter a boast against the Lord.
“Let him who boasts boast in the Lord” (2 Corinthians 10:17 NIV).
